Abstract: CONTRAST CORRECTION ARRANGEMENTS            ABSTRACT OF THE DISCLOSURE         A contrast correction arrangement for use in a color television system includes a plurality of camera tubes each for producing electrical signals corresponding to a dif-ferent primary colour in a scene viewed by the tubes.  A colour coder produces from the camera tubes a composite colour coded signal in accordance with a predetermined broad-casting standard.  Also produced is a signal representative of the greatest brightness in the viewed scene.  A multiplier multiplies the difference between the signal representative of the greatest brightness and a predetermined peak amplitude thereof by a control signal such that a further signal is produced which is variable in both sign and magnitude in dependence upon the departure of the signal representative of the greatest brightness from peak amplitude.  A further multiplier multiplies this further signal with the composite colour coded signal so as to produce a video correction signal of sign varying in dependence upon the sign of the further signal.  A mixer adds the video correction signal to the composite colour coded signal thereby to produce at the mixer output a video signal of compressed, normal or expanded contrast range.

Abstract: ABSTRACT OF THE DISCLOSURE                   For enabling a computer to calculate locations of cuts across an elongated workpiece that will divide it into standardized length finished pieces of optimum economic value, the workpiece is established between parallel, spaced boundaries of an inspection zone, lengthwise parallel to them.  From a movable light source a beam is projected down onto the inspection zone that defines a line of illumination extending from one to the other of the boundaries.  A manually operable control member, movable parallel to the boundaries, actuates the light source to move the line of illumination lengthwise along a workpiece.  An output is produced that has a unique magnitude for each incrementally different position of the line of illumination.  When the line of illumination is located at a boundary between unlike-quality lengthwise extending portions of the workpiece, actuation of a pushbutton delivers the then-existing output magnitude to the computer as an input.

Abstract: METHOD OF RECOVERY OF TAR SANDS MATERIAL            Abstract of the Disclosure A method of recovery of tar sands material from a subterranean layer of such material underlying an overburden comprises sinking a pair of spaced apart mining strings from respective surface rigs down through the overburden and into the layer, and projecting from each string into the material of the layer a jet of water to soften and erode it whereby to form a cavity and generate a slurry of the material and the water.  The water projected from the strings is 80 directed and the spacing of the strings is such that the cavities formed by the respective strings are caused to open into each other.  The slurry is forced up the strings to the surface for recovery of the material therefrom.  The fact that the cavities open into each other enables the slurry forced up one string to be largely the result of water projected from an adjacent string thus minimising the need for a reversal of flow with consequent loss of kinetic energy.  The arrange-ment is also conducive to the use of an entire array of strings.

Abstract: ABSTRACT OF THE DISCLOSURE         An adiabatic calorimeter apparatus disclosed herein is designed for determining the chemical hazard in exothermic or high energy chemical reactions which can result in hazardous runaway reactions and under extreme conditions in an explosion of the reactants.  The reaction vessel is suspended in an insulated chamber.  During the exothermic reaction the adiabatic temperature rise and pressure rise is simultaneously monitored and recorded as a function of time.  A first stage control system maintains the temperature of the reaction vessel in equi-librium with the reaction mix to utilized s conductive electrical resistance heater to heat the reaction vessel to compensate for the heat content (the heat capacity or specific heat multiplied by the mass of the reaction vessel) of the reactor.  The reaction vessel and asso-ciated components in this apparatus closely simulate the structure and operation of a typical chemical plant reactor.

Abstract: RCA 71,823 INRUSH CURRENT START-UP CIRCUIT FOR A TELEVISION RECEIVER INCLUDING A START-UP DECOUPLING CIRCUIT     Abstract Of The Disclosure A start-up circuit for a television receiver includes a circuit for rectifying the AC line voltage and a filter for providing a smoothed DC voltage.  When the receiver is turned on, an initial interval exists in which an inrush current flows into the filter.  A winding, magnetically coupled to an inductor in the path of the inrush current, develops an alternating current potential during the initial interval.  This potential is rectified and provides a start-up operating voltage for the television receiver load circuits.  During the steady state interval, a second circuit provides the operating voltage, and a third circuit couples to the winding a voltage which varies in value from the initial interval to the steady state interval in a manner which decouples the alternating current potential from the load circuits during the entirety of the steady state interval.

Abstract: ABSTRACT OF THE DISCLOSURE   A device for securing a line from  a  boat  to  a  dock  having spaced boards which permits ready engagement and disengagement of the line and dock. The device comprises a body having a shaft and an elongated head secured transversely to one end thereof.  A plate is mounted on the  shaft for slidable movement thereon towards and away from  the head  with  its plane parallel to the head, to provide an  adjustable  but  uniform  space between corresponding points on confronting surfaces of the head  and  the plate. These  surfaces,  during  operation  of  the  device  act  to  grip therebetween planking of the dock. A biasing means is associated with  the shaft and plate to urge the plate  towards  the  head  as  this  space  is increased from a minimum value. The device further comprises  a  means  to which a line from the boat may be secured. This device greatly facilitates mooring a boat or the like to a dock or similar anchor structure  in  that the device, to which a line from the boat has been attached,  need  merely have its head passed longitudinally between adjacent, spaced boards of the dock against the urging of the biasing means, and its body then rotated so that its head is transversely located with respect  to  that  space.   The device thereby grips between the confronting  surfaces  of  the  head  and plate of these boards of the dock.

Abstract: Abstract of the Disclosure An inverter drive circuit is disclosed wherein the inverter is a pulse width modulated inverter.  The inverter includes a regulator circuit to regulate the width of the pulses which control the conduction of first and second controllable semiconductors in the inverter. The regulator is controlled by the output of the inverter in a feedback arrangement with a current limit circuit as well as an instant current limit to limit the output.  A turn-on circuit is utilized to act through a drive transformer to turn on the controllable semiconductors as required.  A turn-off circuit acts on the drive transformer and turns off the turn-on signal.  A set and reset circuit is provided using first and second drive transformers for first and second controllable semiconductors in the inverter.  One transformer is set in order to provide the turn-on and then this transformer is energized in the opposite direction to saturation to obtain a reset.  A decoupling diode is provided between the drive transformer and the control electrode of the semiconductor so that when the decoupling diode ceases conduction then reverse voltage developed by the drive transformer is not applied to the control electrode of the semiconductor.  The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applica-tions, and is not to be construed as a limitation on the scope of the claimed subject matter.
